Detailed Description
The following description of the preferred embodiments of the present invention will be given with reference to the accompanying drawings, so that the function and features of the present invention can be better understood.
The embodiment of the invention comprises a periodontal diagnosis and treatment information management system which comprises a patient terminal, a medical care terminal and a server.
Specifically, the patient terminal is a mobile phone, and the patient terminal interacts with the server through an app or applet in the mobile phone. The medical terminal may employ a general purpose computer, or a mobile device. The server uses an ASP.NET framework, so that development time is saved. The front end interfaces of the patient terminal and the medical care terminal mainly use a Vue frame, and have good interface display effect on users (patients and doctors and test data arrangement). The server may be implemented using various cloud servers. The patient terminal and the medical care terminal are all in communication connection with the server through a network.
As shown in fig. 2, during a patient visit, a doctor interacts with the patient terminal through the medical terminal to obtain the identity of the patient. In one embodiment, the medical terminal has a two-dimensional code scanning device; the medical care terminal obtains the identity of the patient by scanning the two-dimensional code displayed by the patient terminal. In the process, no contact exists between doctors and patients, so that the risk of nosocomial infection can be reduced. After the code scanning, the medical care terminal verifies the identity of the patient in various modes, such as encrypting the two-dimensional code of the patient terminal and adding timeliness, or requiring the patient to provide a mobile phone number filled in during registration.
After the identity of the patient passes the authentication, the doctor enters the diagnosis and treatment process. At which point the patient terminal prompts the patient that the examination procedure is continuing. In the diagnosis and treatment process, a doctor can acquire the identity of a patient and the past examination information through the medical care terminal. During the examination, the doctor fills in the examination information and generates a form. After filling, a doctor submits a form to a server through a medical care terminal, and then the patient terminal prompts the patient to complete the examination process and displays examination information.
In the above process, the inspection information includes: basic data, feature data, and a visualization model.
The basic data includes the number of teeth (including whether there is an implant or not), the number of abnormal roots (bifurcation, curvature, etc.), the condition, the abnormal number of teeth on the occlusal surface, and the tooth distortion shift.
The characteristic data include facial color abnormality (fluorizated plaque, tetracycline tooth), saphenous fissure, fracture, abnormal tooth neck of the crown root, and relationship between tooth and jaw bone.
The basic data are data which can be obtained by general examination, the tooth form, the dental arch form and the dental occlusion relation can be simulated through data comparison after the related data are obtained, and the characteristic data can enable the simulated visual model to be more fit and real.
The visualization model may be generated in a variety of ways.
A visual model is generated by scanning an intraoral scanner. Such as CEREC equipment, which includes an imaging unit for imaging acquisition, bio-reconstruction software, and a grinding unit. The method can obtain a high-precision visual model, has extremely high pertinence, and is suitable for repairing subjects. Therefore, the electronic visual medical record is easy to operate at present, and can be more intuitively understood by a patient when treating the vital teeth and dental pulp mainly in the communication between doctors and patients. This approach requires expensive equipment and cost of use, and not all hospitals or clinics can be configured with high precision scanners and associated procedures. Thus, the process is applicable to initial diagnosis.
As shown in fig. 1, another method for generating a visualization model calculates a visualization model according to basic data, feature data and a standard tooth form model, and obtains key information of the tooth form model of the patient from the detected basic data and feature data, for example: the tooth body long axis, the crown root parting line, the crown root length and the neck margin; different key information for different dental site acquisitions: incisors (incisors, lingual facial fosters, etc.), cuspids (cuspids, lingual facial fosters, etc.), premolars (buccal cusps, lingual cusps, triangular ridges, edge ridges, mesial and distal mesial sulci), molar teeth (mesial and distal buccal cusps, mesial and distal mesial lingual cusps, mesial sulci, central sulci, triangular ridges, edge ridges). And correspondingly adjusting the standard tooth form model according to the obtained key information, and only adjusting the morphological characteristics of the tooth. In this embodiment, the standard tooth form model adopted is a chinese standard tooth form model. The standard tooth shape model is a point cloud model in ply format, and the point cloud data is sparse, so that the adjustment is convenient. After the standard tooth model is adjusted, the Loop subdivision algorithm is utilized to conduct subdivision surface processing on the model, so that the model is more real. And carrying out three-dimensional reconstruction on the model by using a greedy triangulation algorithm, converting the model into a three-dimensional model by using a point cloud model, and transmitting the model to the medical care terminal. The medical care terminal adjusts the tooth position according to the key information of the tooth form, maps and displays the gum and tooth model, and finally presents a visual model. The processing of the model in the background server mainly uses PCL library, and the front-end display part mainly uses thre.
In addition, the historical data of the visual model of the patient can be modified according to the basic data and the characteristic data to obtain the visual model of the diagnosis, through the process, the visual model in the previous diagnosis process can be reused, and in the process of generating the visual model of the diagnosis, the change of the model and the disease progress of the patient can be intuitively observed. The process comprises the following steps:
(1) Obtaining key information of a tooth form model of a patient from the basic data and the characteristic data detected at the time; the key information currently referred to includes (1) dentition (dentition) feature points: the dentition is sharp circle, square circle and ellipse, wherein, whether dislocation teeth and extra teeth are present or not; (2) tooth position characteristic points: whether individual teeth are oversized teeth, too small teeth, stuffy teeth, extended teeth, dental invagination, abnormal tooth positions (including mesial, distal, labial cheek, vertical stuffy teeth), etc.; (3) morphological feature points: form high points of the individual axial surfaces, characteristic points of the dental occlusal surfaces (incisal edges): the incisor ridges and lingual fossa of the incisors; the buccal tip and the lingual tip of the bicuspid teeth form two triangular ridges of the buccal tongue and the near middle sulcus and the far middle sulcus. The mesial, distal buccal tip, mesial, distal lingual tip, 4 edge ridges and 4 point angles, mesial and distal buccal angles, oblique ridges divide the fovea into slightly larger mesial and smaller distal fossa. (4) Tooth pathological feature points: caries progression, pigmentation (endogenous, exogenous), tooth fracturing, etc. The key information to be clinically detected mainly comprises the above (1) dentition (dentition) feature points, (2) dental site feature points and (4) dental pathology feature points.
(2) According to the basic data of the test, returning the data points to the historical data of the last check in a mapping mode; the step refers to that according to key information related to data related in the inspection process, corresponding historical data is obtained from a server, or the server actively sends the corresponding historical data to a client; under certain conditions, if the data related to the current examination is less, the acquisition of all historical data from a server can be avoided, and the network bandwidth is saved; in the process of generating the visual model, only a few key information is processed, so that the calculated amount can be effectively reduced;
(3) Calculating the variation between each key information of the history data of the visual model and the key information detected at the time;
(4) And carrying out affine transformation on the historical data of the visual model according to the variation of each piece of key information to obtain the visual model of the current detection.
Generating a visualization model is one of the core functions of embodiments of the present invention. The function enables medical staff to intuitively observe the past examination results of the patient, and is convenient for the medical staff to compare the change trend among the past examination results, so that the disease progress of the patient can be better known.

The server can generate health advice and corresponding periodontal knowledge articles according to the examination information of the patient, and push or obtain the health advice and the corresponding periodontal knowledge articles to the corresponding patient terminals.
In the applet, a carousel graph may be set on top to show the periodontal knowledge pushed by the server. The physician's orders may also be presented herein. A next result query button may also be provided in the interface of the applet to facilitate patient query of the test results. The system can realize the electronic data record of periodontal conditions, and the traditional paper form is recorded on the internet in a visual mode by utilizing the existing internet technology, so that on one hand, a doctor can conveniently compare periodontal data for a plurality of times, on the other hand, the system is also beneficial to the patient to know the periodontal conditions of the patient, and on the other hand, if the patient needs to make a consultation or needs to go to other places to visit, the doctor can conveniently know the past conditions of the patient.
In addition, the health advice and the corresponding periodontal knowledge articles can be pushed by a WeChat public number, on one hand, the daily periodontal knowledge and the small common sense of oral science can be pushed, on the other hand, the expert in the related field of problem consultation related to periodontal diseases proposed by people can be pushed out finally to be known, and of course, the public number can push the latest knowledge and the frontier content in periodontal knowledge, so that the patients can know the related situation of periodontal diseases conveniently.
The last part is a periodontal doctor visit reminder, which can be used for providing a background for accessing a hospital and directly pushing reservation information to a patient, or manually inputting reservation conditions by the patient, and introducing the periodontal doctor to the patient by using a plain language or providing oral advice necessary for the patient after each doctor visit.
